    摘要： A method for designing a device that comprises a first semiconductor chip, a second semiconductor chip and an adjustment target is disclosed. The first semiconductor chip comprises an input pad, a first power supply pad and a first ground pad. The second semiconductor chip comprises an output pad coupled to the input pad. The adjustment target is connected to the first and the second semiconductor chips. A main target variable is calculated from an input circuit chip model, an output circuit chip model of the second semiconductor chip in frequency domain and a target impedance model of the adjustment target in frequency domain. The input circuit chip model is created by representing the first semiconductor chip in frequency domain in consideration of a first capacitor model between the input pad and the first power supply pad, a second capacitor model between the input pad and the first ground pad, and a chip internal capacitor model between the first power supply pad and the first ground pad. The main target variable is compared with a predetermined constraint represented in frequency domain to decide design guidelines for the adjustment target.

Further, it clearly indicates a flow of electromagnetic energy on the surface or in the circumference of the electronic apparatus by applying mathematical treatments to a magnetic field distribution at circumferential positions of the electronic apparatus. Thus, a distribution of high-frequency electric field generated from the electronic apparatus is measured with high accuracy.

    摘要： Provided is a noise equivalent circuit for completing an EMC analysis in a practical time and through a low-cost calculation process at an upstream stage of system design. The noise equivalent circuit includes one or more energy sources; a propagation path for propagation of energy from the energy source including a conductive path such as a cable and an electromagnetic field coupling path due to the coupling of an electric field and a magnetic field with another electronic device or cable; and a GND port connected to a system, and each port is represented by the noise voltage source or the noise current source and the internal impedance. This noise equivalent circuit can determine an external impedance that is varied depending on a load connected externally or the distance from an external device or a cable, whereby the noise of the system as a whole can be analyzed.
